Divided and this application filed January 19, 1918. Serial No. 212,658.

To all whom it may concern:

Be it known that 1,,GLAUD C. CRAVEN, a citizen of the United States, residing at Kansas City, in the county ofJaokson and State of Missouri, have invented certain new and useful Improvements in Agricultural Machines, (the same being a division of my prior Patent No. 1,224,716, dated May 1, 1917,) of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improve ments in agricultural machines and has relation more particularly to a device ofthis general character especially designed and adapted for use in the working of soil, and it is an object of the invention to provide a device of this general character which is adapted to work the soil at a plurality of points transversely ofthe dlrectlon of travel of the machine and wherein certain of the ground engaging elements may. be raisedor lowered independently of. the remainder of said elements.

It is also an object of the invention to provide a machine of this general character having novel and improved means whereby it may be employed with equal facility as a cultivator or plow.

An additional object of the invention is to provide a novel and improved machine of this general character which .may be employed as a cultivator in connection with a plurality of rows and whiclnmay be employed to turn apluralityof furrows.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved agricultural machine whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features ofmy invention will hereinafter be definitely claimed.

In order thatmy invention maybe the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure 1 is a view in top plan of an agricultural machine constructed in accordance with an embodiment of my invention;

Fig. 2 is a view in side elevation of my improved machine as herein disclosed;

Fig. 3 is a fragmentary transverse sectional view taken through the forward portion of my improved machine with certain of the parts omitted;

Fig. 4 is a view in top plan illustrating an agricultural machine arranged in accordance with a further embodiment of my ininwardly of the rear end portions are the bearings 5 mounted upon the shaft 6 and between the beams 4 is the traction wheel 3 adapted to be driven by the motor M.

' The forward end portions of the beams 4 are rested upon thetransversely disposed auxiliary frame A. This frame A embodies the parallel beams 14 suitably connected at their terminals by the castings 14. The beams 14 are provided with a series of longitudinally spaced openings 15 through which the bolts 12 or other fastening elements are disposed in order to secure the beams 4 to the auxiliary frame A. The bolts 12 or the like are removable so that in accordance with the requirements f practice the mounting of the beams 4 upon the frame A may be. adjusted longitudinally of said frameor in a direction transverse of the frame F.

Coacting with the opposite end portions of the auxiliary frame A are the steering wheels 2, the construction'and operation of which being particularly described and claimed in my Patent No. 1,224,? 16 dated May 1, 1917, and of which the present application is a division.

Depending from the frame A at each side of the center thereof is a pair of longitudinally alined bearings or supports 16 with which are engaged the extremities of a rod 18. The structure results in a rod 18 being positioned at opposite ends of the frame A and in longitudinal alinement.

Extending upwardly from the opposite end portions of the frame A are the bearings or supports .19 and engaged with said bearings orsupports 19 and the forward end portions of the beams 4 are the rods 20.

Pivotally engaged as at 25 with each of Patented May 6, 1919.

the rods 18 and 20 are the beams 21 and 21 of the frames 22 and 22 and which frames are provided with the ground engaging elements E of a cultivator type. The beams 21 engaging the rods 20 are arch-ed inorder to prevent said beams from offering any obstruction to the steering wheels 2.

Disposed transversely of the frame F is the shaft 29 provided with the rock arms 29 with one of which is engaged the rod 31. The rod 31 is directly connected with the frames 22. Operatively engaged with the second rock arm 29 is the rod 28 which is also engaged with the lever 26. It will be self-evident that upon swinging the lever 26 in one direction, theframes 22 willbe elevated and vice versa in accordance with the requirements of practice.

Also rotatably supported by theframe F is a second transversely disposed rockshaft 33 provided with rock arms 33 with which are engaged the rods. 35 directly engaged with the outer or side frames 22; The shaft 33 is also provided with the crank arm 33 with which is engaged the rod 32 also operatively engaged with the second-lever 27 It will be self-evident that upon proper manipulation of the lever 27 the outer or side frames 22 may be raised or lowered-inaccordance with the requirements of practice.

As herein disclosed thebearings 30 and 34 for the shafts 29 and 33 respectivelyare carried by a beam or bar 36 disposed transversely of the frame F and suitably secured to the side beams 4 thereof.

As disclosed in Figs. 1, 2 and 3 my im proved machine is assembled for cultivation in connection with a plurality of rowsand it is to be particularly noted that when the occasion of practice requires the intermediate frames 22 may be elevated independently of the outer frames 22 or vice versa, or if desired both sets of frames 22 and 22 may be elevated by imparting'the proper pull upon the levers 26 and 27 In the form of invention illustrated in Figs. 4 and 5 I show my improved machine employed in connection with ground engaging elements of a plow type. hen in use the beams 4 are adjusted longitudinally of the auxiliary frame A to position the same substantially to one side of the longitudinal center. The depending plates or supporting arms 112 are secured to the forward end portions of the beams A and pivotally engaged with said plates or arms 1112..are the beams 110 of the plows P and which beams are connected as indicated at '110 so that the plows P are assembled ingang. The depending rod 31 of the shaft 29 inthis instance is engaged with the connecting member 110 so that the plows P may be raisedor lowered as may be desired by the requirements of practice. In adjusting the arms 4: of theframe F to one end of the broken.

From the foregoing description, it is thought to be obvious that an agricultural machineconstructed in accordance with my inventionis particularly well adapted for use by reasonof the convenience and facility with whichiit may-be assembled and operated audit will also be obvious that my invention issusceptible of some change and modification without departing from the principles and spirit zthereof and for 'this reason I .do not wishto be understood as limiting myself to the precise arrangement and formation 4 of the several gparts herein shown in carrying out my invention in practice except as hereinafter claimed.
